& WARNING
• Do not park or operate the vehicle in areas where the hot
exhaust sy stem may come in conta ct with dry gra ss, bru sh, fuel
s pill or oth er mater ial wh ich can caus e a fire .
• Do not apply additional under co ating or ru stproofing on or
near the exhaust manifold, exhaust p ipes, catalytic converter or
heat shield s. During driving, the sub stance u sed for undercoating
c ould overheat and cause a fire .
0 Note
• Be aware that j ust one tank fi lling w it h le aded fuel w ill already
seriously degra de the performance of the catalyt ic converter .
• Do not exceed the correct engine o il leve l~
page 23 2.
• Do not dr ive until t he f uel tank be comes comp lete ly empty. The
eng ine could misfire . Unburned fue l cou ld also get into the exhaust
sys tem and t his co uld cause t he ca talyt ic conver ter to ove rhe at.
• Do not t urn off the ignition while the vehicle is moving .
• Do not continue to operate your vehicle under these conditions, as
otherwise fuel can reach the cata lytic converter. This cou ld resu lt in
over heat ing of the converter, req uir ing its rep lacemen t.
• T o ass ure efficient operation of the Emission Contro l System :
- Have your ve hicle maintai ned properly and in accordance with
t he se rvi ce recommenda tions in your Warran ty

- Lack o f prope r mai ntena nce as well as improper use of the
vehicle w ill impa ir the f unct io n of the emission control system and
co uld lead to damage .
<£> For the sake of the environment
Even when the Emission Contro l System is operating p roperly, the
exhaust gas ca n have a sulfur-like exhaust gas smell under some

Diesel particu ate filter
The diese l particulate filte r filters nearly all of the soot part icles out
of the exhaust. The filte r cleans itself a utomat ically under normal
dr iv ing cond itions . If the fi lter cannot clea n itself (for example,
because you are only driving short distances), the filter becomes
clogged w it h soot and the symbol fo r the diese l particulate fi lter
ill uminates ~
page 34.
& WARNING
• Do not park your vehicle over flammable materials such as
grass or leaves because the high temperature of the diesel partic­
ulate filter could start a fire .
• Do not apply an underbody prot ectant in the exhaust system
area or a fire could start.
[I) Tips
• When the diesel partic ulate f ilter becomes sat urated, the engine
speed increases to approx ima tely 1 ,S00 rpm w hile the vehicle is in
motion to initiate t he cleanin g of the diesel particulate fi lter auto ­
matically w it h out the wa rning lamp ligh ting up. If the war ning lamp
st ill appears, you sho uld drive to a qualified workshop. •
Avoid damaging the vehicle
When you are driving on poor roads, or ove r curbs, steep ramps, etc .,
m ake ce rta in t hat low-ly ing pa rt s such as spoilers and exhaust system
parts do not bottom out and get damaged.
Vehicle care Do-it-yourself service Technical data

Driving and environment
This is especially true for vehicles with low-slung chassis (sports
chassis) and fully loaded vehicles. •
Operate your vehicle economically
and minimize pollution
General
Your personal style of driving will determine the economy
of your vehicle, as well as exhaust and noise levels.
Fuel economy, env ironmental impact, and wear on your eng ine,
brakes and tires largely depend on three factors:
• your personal driving style
• operat ing conditions
• technical lim itations
If you anticipate what you need to do next and drive economically,
you can easily cut your fuel consumpt ion by 10-15 percent. This
sect ion wi ll g ive you some tips on how you can help the environment
and your pocketbook.
[I) Tips
The consumption estimates as published by ENVIRONMENTAL PROTECTION AGENCY (EPA) and Transport Canada may not co rre­
spond to your actual consumption on the road, which will vary
depending upon vehicle load and speed, road and weather conditions,
trip length, etc. •
Drive smoothl} and keep a lookout ahead
Vehicles use the most fuel when they are accelerating.
Avoid unnecessary accelerating and braking .
Vehicles use the most fuel when they are accelerating. If you antici­
pate what is go ing to happen next, you will need to brake less and,
thus, accelerate less. Let the vehicle coast whenever possible - for example when you see that the next traffic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and improves your
mileage.
- Try and keep well below your car's maximum speed.
Accelerating gently reduces fuel consumption, engine wear, and does
not d isturb the env ironment.
Fuel consumption, exhaust emissions and engine noise increase
disproportionately at high speeds. If you drive at approximately three
quarters of top speed, fuel consumption will be reduced by one half.
Never drive faster than the posted speed limit and weather condi ­
tions perm it. •
Reducing unnecessary idling
Even when your car is just idling it burns up fuel.
- Shut the engine off when you are not driving the vehicle .
- Do not warm up the vehicle by letting the engine run at idle .
It makes sense to shut off the engine in traffic jams, when waiting for
trains to pass at railroad crossings, or at traffic lights that have long
wa its on red. Turn ing the eng ine off for just 30-40 seconds saves
more fuel than is burned starting the engine again.
It takes a long time for the engine to warm up fully when it is running
at idle. However, wear and noxious emissions are espec ially high
when the engine is warming up . So you shou ld drive away as soon as .,_

Driving and environment
------------------------------------------------'
you start the engine and avoid running at high RPMs while the engine
is still warming up.
0 Note
Do not leave engine idling unattended after starting. If warning
lights should come on to indicate improper operation, they would go
unheeded. Extended idling also produces heat, which could result in
overheat ing or other damage to the vehicle or other property.•
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel.
- Have your vehicle serviced at regular intervals.
By having your vehicle regularly serviced by an authorized Audi dealer
helps to ensure that it runs properly and economically. The condition
of your vehicle not on ly affects its safety and ability to hold its value,
it also affects
fuel consumption .
Check your oil each time you fill your tank.
The amount of oil used is related to engine load and speed.
It is normal for the oil consumption of a new engine to reach its
lowest value after a certain mi leage has been driven.
You must drive you r vehicle about 3,000 miles (5,000 kilometers)
before you can properly assess oil consumption.
Thi s also applies to fuel consumption and engine output.
0 Note
• Have your vehicle maintained properly and in accordance with the
service recommendations in your Warranty
& Maintenance booklet.
Lack of proper maintenance as well as improper use of the vehicle will
impa ir the function of the emission control system and could lead to
damage.
Controls and equip­ ment Safety first Vehicle operation
•
Do not alter or remove any component of the Emission Control
System unless approved by the manufacturer.
• Do not a lter or remove any device, such as heat shie lds, switches,
ignition w ires, va lves, which are designed to protect your vehicle 's
Emission Control System and other important vehicle components.
Fewer short tr ips
Fuel consumption will always be relatively high on short
trips.
- Try to avoid driving short distances with a cold engine.
The engine and catalytic converter have to reach their optimal oper­
ating temperature
to reduce fuel consumption and noxious emis ­
sions effectively .
• Just after starting, a cold eng ine in a mid-size car burns the fuel at
a poor rate of 6-8 miles per gallon (30-40 l/l00km). Half a mile down
the road, the mileage improves to 12 MPG (20 l/100 km). It will take
the engine no less than
two and a half miles (4 km) of driving to
warm up to its proper operat ing temperature and operate at an
economic mileage . This explains why taking the car for sho rt trips is a
rather wasteful convenience .
• Th e
outside temperature is also critical in this regard . Your car
consumes more fuel in the winter than in the summer.

High temperatures, as from exposure to intense sunlight, intensify
the corrosive effect particularly when humidity is high as well.
Under certa in circumstances,
weekly washing may be necessary .
Under other conditions, a month ly washing and waxing may be
adequate.
After the winter, the underside of the vehicle should be thoroughly
washed, preferably in a profess ional car wash.
& WARNING
Always read and heed all WARNINGS and other information
=> page 206.
0 Note
You should remove debris (such as insects) from the headlight lenses
on a regular basis, for example when refueling yo ur vehicle. Never
clean the headlights with a dry cloth or sponge. Use a wet cloth or
sponge. It is best to use soapy wate r.•
Automatic car wash
The vehicle can be washed in almost any modern auto­
matic car wash.
The vehicle paint is so durable that the vehicle can normally be
washed without problems in an automatic car wash. However, the
effect on the paint depends to a large extent o n the design of the
facility, the filtering of the wash water, the type of wash and care
material, e tc. If the paint has a dull appearance after going through
the car wash or is scratched, bring this to the attention of the oper­
ator immediately .
If necessary, use a different car wash.
Before going through a car wash, be sure to take the usual precau­
tions such as closing the windows and panoramic sliding sunroof*.
Remove ante nna if applicable.
Safety first
If you have installed additional accessories on the vehicle - such as
spoilers, roof rack, etc. - it is best to ask the car wash operator if these
should be removed.
& WARNING
Always read and heed all WARNINGS and other information
=>page 206. •
Washing the vehicle by hand
A lot of water is needed when washing a vehicle by hand.
-Before you start wash ing, ma ke sure you have read and
understood the WARNINGS ~
& in "General informa­
tion" on
page 206.
-First soak all dried dirt until it is soft, then rinse it off.
- As you clean your vehicle, start with the roof and work your
way down to the bottom, using a sponge, a sponge glove
or a clean brush.
- Rinse the sponge or the sponge glove often, flushing it
clean each time.
- Use special car shampoo only for very persistent dirt.
- Rinse the car thoroughly with water .
- Use a chamois leather to gently wipe the exter ior dry .
Use a separate sponge for cleaning the whee ls, door s ills and other
regions exposed to road dirt. In this way, you will not scratch the
paint with coarse particles imbedded in the sponge the next time you
wash the car . .,,

Engine compartment
Be especially careful when cleaning the engine compa rt­
men t.
Always switch off the ignition before cleaning the engine=:>& .
Plenum panel
Remove leaves from the plenum panel in front of the win dshi eld
unde r th e eng ine hood . T hi s prevents the water d rain holes from
becoming b locked, and it prevents debris from entering the vehicle
inter io r th rough the heat ing and vent ilation ducts .
Corrosion protection
The eng ine compartment and transmission have been cor rosion­
protected at the factory.
Good ant i-cor rosion treatment is very impo rtant , pa rtic ular ly in the
w inter . If the vehicle is frequently driven on sa lt treated roads, the
en tire eng ine compar tment and plenum p anel sho uld be thoroug hly
cleaned at the end of winter and retreated to prevent salt damage. At
t he same t ime, the underside of the vehi cle should be washed as well.
If the e ng ine compartment is clea ned at any t ime with grease

5>, or i f you have the engine washed , the anti ­
co rros io n treatment is a lmost a lways removed as w ell.
It is t herefore
essential to have a long-last ing corrosion p rotect ion reapplied to all
surfa ces, seams, jo ints and compo nents in the engi ne co mpa rt ment .
& WARNING
Be aware: The engine compartment of any motor vehicle is a
potentially hazardous area .
• Before working in the engine compartment, be sur e to read the

Using the right fuel helps keep the environment clean and
prevents engine damage .
Fuel recommendation
The fuel recommended for your vehicle is unleaded premium grade
g asoline . See also :::>
page 296, "D ata ". Aud i recommends using TO P
TIER Detergent Gasoline with a minimum octane ra ting of 91 AKI (95
R O N). For more information on TOP TIE R Detergen t Gasoline, please
go to the official website (www. toptiergas .com) .
Th e recommended gasoline octane rating for your engine can also be
found on a labe l located on the ins ide of t he fue l fille r flap. This rating
may be specified as AKI or RON .
Your vehicle may also be ope rated us ing unleaded reg ular gasoline
with a minim um octane rating of 87 AKI/91 RON. However, us ing 87
AKI/91 RON octane fuel will slig htly reduce engine performance.
Use un leaded ga soline only. U nleaded gaso line is available
throughout the USA, Canada, and in most E uropean co untries. We
recommen d that you do not ta ke your veh icle to areas or co unt ries
where unleaded gasoline may not be available.
F or more in formation on re fueling yo ur vehicle, see:::>
page 221.
Octane rating
Octane r ati ng indi cat es a gaso line's abi lity to resis t engi ne damag ing
"knock" caused by premature ignition and detonat ion. Therefore,
buying the correc t g rade o f gasol ine is very impo rtan t to help preve nt
possible engine damage and a loss of engine performance .
Gaso line most common ly used in the United States and Canada has
the following octa ne rat ings tha t ca n usually be fou nd on the filler
pump :
Safety first
• Premium Grade: 91 - 96 AKI
• Regular Grade: 87 - 90 AKI
Explanation of t he abb reviations :
AKI= Anti Knock Index= (R +M)/2 = (RON+ MON)/2
RO N= Research Octane Number
M ON= M otor Octane Num ber.
0 Note
• Do not use any fue l with octane rat ings lower than 87 AKI o r 91
RON otherwise expens ive engine damage will occ ur.
• Do
not use leade d gasoline! The use o f leaded gaso line will
severely damage your veh icle 's cata lytic converter and its abi lity to
cont rol exhaust emissions .•
Blended gasoline
Use of gasoline containing alcohol or MTBE (methyl
tertiary butyl ether)
Yo u may use unleaded gasoline blended w ith alcoho l or MTBE
( c ommon ly referred to as oxygenates) if the blended mix ture meets
the following criteria:
Blend of ga soline methanol (wood alcohol or methyl alcohol)
• Anti -k nock index m ust be 87 AKI or h igher .
• Bl end must con tain no mo re t han 3% methanol.
• Blend must contain more than 2% co-solvents.
Blend of ga soline and ethanol (grain alcohol or ethyl alcohol)
• Anti-knock index must be 87 AKI o r higher.
• Bl end must no t contain more th an 10% ethanol.
Vehicle care Technical data

Fuel supply and filling your fuel tank
Blend of gasoline and MTBE
• Anti-knock index must be 87 AKI or higher.
• Blend must contain not more than 15% MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform especially well fo r
winter or summer driving. During seasonal change-over, we suggest
that you fill up at busy gas stat ions where the seasonal adjustment is
more likely to be made in time.
0 Note
• Methano l fuels which do not meet these requirements may cause
corrosion and damage to plastic and rubber components in the fue l
system .
• Do not use fuels that fail to meet the specified criteria in this
chapter .
• If you are unab le to determine whether or not a particu lar fuel
blend meets the spec ifications, ask your serv ice station or its fuel
supplier.
• Do not use fuel for which the contents cannot be identified.
• Fuel system damage and performance problems resulting from
the use of fuels different from those specified are not the responsi­
bility of Aud i and are not covered under the New Vehicle or the Em is­
sion Control System Warranties.
• If you experience a loss of fuel economy or driveab ility and perfor­
mance problems due to the use of one of these fuel blends, we
recommend that you switch to unblended fuel.•
Gasoline additives
A major concern among many auto manufacturers is carbon deposit
build-up caused by the type of gasoline you use. Although gasoline grades differ from one manufacturer to another,
they have certain things
in common. All gaso line g rades contain
substances that can cause deposits to collect on v ital engine parts,
such as fuel injectors and intake valves. A lthough most gasoline
brands include additives to keep eng ine and fuel systems clean, they
are not equally effective.
Audi recommends using TOP TIER Detergent Gasoline. For more
information on TOP TIER Detergent Gasoline, please go to the officia l
webs ite (www.toptiergas.com).
After an extended period of using inadequate fuels, built-up carbon
deposits can rob your engine of peak performance.

Applies to veh icles: wit h diese l eng ine
Diesel fuel
Always use ULSD (Ultra Low Sulfur Diesel) sulfur content
15 ppm or less.
Th e ULSD (Ultra Low Sulfur Diesel) meets the ASTM-D -975 (grade 2).
Diesel fuel with a higher concentration than ULSD-Diesel No. 2
ASTM D975 and Bio-diesel with a higher concentration than S
%
like Bll, B20 or BlOO are strictly prohibited.
Service station fuel pumps are labeled with the correct fuel informa­
tion for easy recognition by the user. If the diesel fuel pump is not
labeled ask the station operator what fuel is being dispensed before
filling up your vehicle.
Service stations offering diesel fuel are generally located on truck
routes or major highways . D irectories of diesel fuel stat ions are
usually available at diesel fuel stations.
